Air is supplied and exhausted
intermittently when the vacuum
decreases.
Air is supplied and exhausted
continuously during the adsorption
of the workpiece.
During operation of energy sav-
ing function, if the switching of
vacuum stop/generate has
reached the ‘Count value’, ener-
gy saving operation automatical-
ly switches to continuous ad-
sorbing to prevent excessive
valve operation.

An I/O data connected to an SI unit can be
controlled and checked by multiple I/O
controllers (PLC).
Example: PLC1 controls the valve while PLC2 checks
pressures or diagnostic data.
PLC q PLC w PLC e PLC r¡ Information can be shared with up to 3
controllers in addition to the control PLC.
¡ The cost of the hardware, cables, and
installation space can be reduced.
Example: PLC4 controls the valves and checks
pressures. Information of PLC4 is shared
and monitored by PLC1 to 3.
∗ The Shared Device function enables an I/O module connected to the I/O device to be controlled by multiple I/O controllers (PLC). The control status can be shared
among other I/O controllers. As the function can be used across the entire PROFINET line, the cost for hardware, cables, and installation space can be reduced.

How to Read the Flow Rate Characteristics Graph
The fl ow rate characteristics indicate the relationship between the vacuum pressure and the suction
fl ow of the ejector. They also show that when the suction fl ow changes, the vacuum pressure also
changes. In general, this indicates the relationship at the ejector’s standard operating pressure.
In the graph, Pmax indicates the max. vacuum pressure, and Qmax indicates the max. suction fl ow.
These are the values that are published as specifi cations in catalogues, etc. Changes in vacuum
pressure are explained in the order below.
1. If the ejector’s suction port is closed and sealed tight, the suction fl ow becomes “0,” and the
vacuum pressure increases to the max. (Pmax).
2. If the suction port is opened gradually and air is allowed to fl ow (the air leaks), the suction fl ow
increases, and the vacuum pressure decreases. (The condition of P1 and Q1)
3. If the suction port is opened completely, the suction fl ow increases to the max. (Qmax), while the
vacuum pressure then drops almost to “0” (atmospheric pressure).
As described above, the vacuum pressure changes when the suction fl ow changes. In other words,
when there is no leakage from the vacuum (V) port, the vacuum pressure can reach its maximum,
but as the amount of leakage increases, the vacuum pressure decreases. When the amount of
leakage and the maximum suction fl ow become equal, the vacuum pressure becomes almost zero.
When adsorbing workpieces which are permeable, subject to leakage, etc., caution is required as
the vacuum pressure will not be very high.

Specifi c Product Precautions 1Be sure to read this before handling the products. Refer to the back cover for safety in-
structions. For vacuum equipment precautions, refer to the “Handling Precautions for SMC
Products” and the “Operation Manual” on the SMC website: https://www.smc.eu
Design / Selection
Caution1. For specific product precautions on solenoid
valves, refer to the solenoid valve (JSY3000 series) catalogue.
2. For specific product precautions on pressure sen-sors, refer to the pressure sensor (PSE54� series) catalogue.
Supply Valve / Release Valve
Warning1. Manual override operation
Regardless of an electric signal for the valve, the manual over-ride is used for switching the main valve. Connected actuator is started by manual operation. An alarm may occur when us-ing the manual override during PROFINET communication. Use the manual override when the power supply is turned off.
Manual override is non-locking push type. Push the manual override with a screwdriver of a diameter smaller than indicat-ed in the diagram until it reaches the end.
2. Energization
When workpiece is being adsorbed, please keep generating the vacuum pressure to prevent the workpiece from dropping. Do not perform the operation to generate vacuum and release pressure at the same time as this may cause malfunction.
Design / Selection
Warning1. Confirm the specifications.
Products represented in this catalogue are designed only for use in compressed air systems (including vacuum).
Do not operate at pressures, temperatures, etc., beyond the range of specifications, as this can cause damage or malfunc-tion. (Refer to the specifications.)Please contact SMC when using a fluid other than compressed air (including vacuum).We do not guarantee against any damage if the product is used outside of the specification range.
2. Do not use the product to drive an actuator such as a cylinder (when release pressure is constantly applied).
Failure to do so may lead to performance issues or damage to the body of the product.
3. Vacuum pressure
Since valves are subject to air leakage, they cannot be used for applications such as holding vacuum in a pressure vessel. SMC can issue no guarantees regarding the maintenance of workpiece adsorption when using check valves. Take separate safety measures to prevent workpieces from dropping in the case of an electrical power outage, etc.
4. Cannot be used as an emergency shutoff valve, etc.
The valves presented in this catalogue are not designed for safety applications such as an emergency shutoff valve. If the valves are used in this type of system, other reliable safety assurance measures should also be adopted.
5. Release of residual pressure
For maintenance and inspection purposes, ensure to install the residual pressure release system when piping.
6. Vacuum adsorption
At the time of vacuum adsorption, be sure to supply a constant supply of vacuum. Failure to do so may result in foreign matter sticking to the adsorption pad or air leakage, causing the work-piece to drop.
7. Ventilation
Provide ventilation when using a vacuum ejector in a confined area, such as in a closed control panel. For example, install a ventilation opening, etc., in order to prevent pressure from increasing inside of the confined area and to release the heat generated by the valve.
8. Extended periods of continuous energization
If a valve will be continuously energised for an extended peri-od of time, the temperature of the valve will increase due to the heat generated by the coil assembly. This will likely adversely affect the performance of the valve and any nearby peripheral equipment. Therefore, if the valve is to be energised for periods of longer than 30 minutes at a time, or if during the hours of operation the energised period per day is longer than the de-energised period, we advise using a N.O. (normally open) valve.
9. Resumption after a long period of holding time
When resuming operation after a long period of holding time, there are cases in which, regardless of whether the product is in an ON or OFF state, there is a delay in the initial response time due to adhesion. Conducting several cycles of running-in operation will solve this problem. Please consider implement-ing this before resumption.

Replacement Procedure
Caution1. Replacement Procedure for Filter Element
1) To pull out the vacuum port adapter, rotate the adapter by about 90 degrees in direction A and pull in direction B. The adapter can be removed with the fi lter element from the sealing valve body.
2) Remove the fi lter element from the vacuum port adapter and replace it with a new fi lter element.
A
B
3) When installing the fi lter, insert the fi lter to the end so that there is no gap∗1 or bending∗2 between the fi lter and the vacuum port adapter.A gap or bending will cause interference with internal parts, the fi lter element to deform and deterioration of the perfor-mance.
4) Put the fi lter element back into the sealing valve body fol-lowing this procedure in reverse.
¡ To mount the vacuum port adapter into the sealing valve body, turn the adapter so that the mark of the adapter is on top (rotation stops there.).
¡ If it is diffi cult to remove the vacuum port adapter, you can remove the adapter with a hexagon wrench using the hex-agonal hole in V port. The table shows the port size and the width across fl ats.

Warning3. LED indication
Red LED turns on when supply valve is energised. Green LED turns on when release valve is energised.
4. Air leakageZero air leakage is not guaranteed for the supply valve or release valve.
Be aware that because there is a chance of air and vacuum leakage, the pressure may change if the V port side is tightly sealed.
Manual Override for Residual Pressure Release
WarningV port is released to atmosphere when performing the manual override for residual pressure release. Please perform after ensuring measured are in place to prevent the workpieces from dropping, etc.

Replacement Procedure
Caution3. When only replacing the sound absorbing material
(for high-noise reduction silencer exhaust)
1) Use the notch to remove the cap.
2) Use a precision screwdriver to remove the sound absorbing
material.
3) Insert the new sound absorbing material, and return the
cap.
Ejector Exhaust / Exhaust Noise
Caution1. Ejector exhaust
The exhaust resistance should be as small as possible to ob-
tain the full ejector performance. There should be no shield
around the exhaust slit for silencer exhaust type.
For port exhaust type, ensure that the back pressure does not
exceed 5 kPa. Increased back pressure may lead to the re-
duction of suction fl ow and delays in the transport cycle time.
Do not operate the ejector or apply pressure to the exhaust
port with the exhaust port closed. This increases the pressure
in the product and can damage the vacuum ejector.
2. Sound absorbing material
If the sound absorbing material is clogged, it will cause a re-
duction in the ejector performance.
Sometimes, if the operating environment contains a lot of par-
ticles or mist, the replacement of the fi lter element only is not
enough to recover vacuum performance - as the sound ab-
sorbing material may be clogged.
Replace the sound absorbing material. (Regular replacement
of the fi lter element and the sound absorbing material is rec-
ommended.)
Replacement Procedure
Caution2. Replacement Procedure for High-noise Reduction
Silencer Assembly
1)Flip the ejector.
2) To remove the clip that holds the High-noise reduction si-
lencer, insert a precision screwdriver. Move the screwdriver
to pull out the clip.
3) Remove the high-noise reduction silencer.
(Procedure to put parts back together)
4) Insert the High-noise reduction silencer and insert the clip
into the groove. (Push completely to the end.)
∗ Do not pull or bend the two projections at the end surface of the
diffuser. These are spacers to prevent the displacement of the
diffuser and they may break if force is applied.

How to Mount a Manifold
Caution1. Do not drop, hit, or apply excessive impact to the
product when handling it.Even if the body looks undamaged, the internal components may be damaged, leading to a malfunc-tion.
2. Load to the body
The product body is made of resin; therefore, do not apply load
to the port after mounting. Prevent any kind of operation which
generates moment as this may cause reduced performance or
damage to the body.
3. Installation
Manifold can be mounted onto the fl oor using M6 holes on the
end plate. The DIN rail installed in the product is used for con-
necting the ejectors. Do not use mounting holes of the DIN rail
to mount the product.
4. Ensure sufficient space for maintenance activities.
When installing the products, allow access for maintenance
and inspection.
Vacuum Break Flow Adjusting Needle
Caution1. The flow rate characteristics show the representa-
tive values of the product itself.
They may change depending on piping, circuit and pressure
conditions, etc. The fl ow rate characteristics and the number
of needle rotations vary due to the range of the specifi cations
of the product.
2. The needle has a retaining mechanism, so it will not turn further when it reaches the rotation stop posi-tion.
Turning the needle too far may cause damage.
3. Do not tighten the handle with tools such as nip-pers.
This can result in breakage due to idle turning.
4. Do not over tighten the lock nut.
It is possible to tighten the standard lock nut (hexagon) manu-
ally.
When tightening further with tools, tighten by approximately
15° to 30°. Over tightening may cause breakage.
5. When vacuum break fl ow adjusting needle screw-driver operation type (-E) is selected as option, make sure the lock nut is not loose to prevent the nut from coming off due to vibration.
�Vacuum Release Air
When fully closed, leakage cannot be prevented completely.
There is an allowance for a certain amount of leakage in the
product’s specifi cations. Tightening the needle to reduce leak-
age to zero may result in equipment damage.
Ejector Exhaust / Exhaust Noise
Caution3. Exhaust noise
When vacuum ejector generates vacuum, noise can be heard
from the exhaust port when the standard supply pressure is
close to the pressure that generates peak vacuum pressure
making vacuum pressure unstable. If the vacuum pressure
range is adequate for adsorption, there should not be a prob-
lem. If the noise causes a problem or affects the setting of the
SI unit, change the supply pressure slightly to avoid the pres-
sure range of the noise.
0
Models with a large nozzle diameter generate a large exhaust
noise if the exhaust (EXH) port is opened. Install piping or a
silencer to the exhaust port to reduce the exhaust noise.
4. Exhaust air
If solid substances are sucked in through the vacuum (V) port,
they will be discharged from the exhaust port at a high speed if
the exhaust (EXH) port is opened. Therefore, do not look into
the exhaust port or direct the exhaust port toward a person
when the ejector is operating.
Operating Supply Pressure
CautionUse the product within the specifi ed supply pressure range.
Operation over the max. operating pressure can cause damage
to the product.
The parts around the vacuum port of this product are designed to
be used with vacuum pressure.
Port Size
Caution1. Air pressure supply (P) port
P port (End plate U) and P port (Ejector) are connected inside.
For an adequate performance, the number of stations when
operated simultaneously depends on the nozzle diameter.
Refer to page 11 for the number of stations that can operate
simultaneously for each ejector size.

Adjustment / Operation
Caution1. Please refer to the PLC manufacturer's manual, etc.
for details of the SI unit programming and addresses.
The programming content related to the protocol is designed
by the manufacturer of the PLC used.
2. For the first operation, always perform zero clear
with no pressure applied.
Operating Environment
Warning1. Do not use in an atmosphere containing corrosive
gases, chemicals, sea water, water, water steam, or
where there is direct contact with any of these.
2. IP65 enclosure: The protection structure against
solid foreign objects is dust-tight type and the pro-
tection structure against water is water-jet-proof
type.
Dust-tight means that no dust can enter the inside of the
equipment. Water-jet-proof means that the product is not ad-
versely affected by direct water jets from any direction. That is,
even when direct water jets are applied to the product for 3
minutes by means of the pre-determined method, there is no
water entry that hinders the correct operation inside the equip-
ment. Be sure to take appropriate protective measures if the
product is to be used in an environment where it will be con-
stantly exposed to water or fl uids other than water splash. In
particular, the product cannot be used in environments where
oils, such as cutting oil or cutting fl uid, are present.
3. IP65 is achieved when the following conditions are
met.
1) Provide appropriate wiring between the SI units using elec-
trical wiring cables, communication connectors, and cables
with M12 connectors.
2) Suitable connecting of connectors for supply valve and re-
lease valve assembly, pressure sensor assembly and the
control unit.
3) Suitable mounting of SI Unit, control unit and vacuum ejec-
tors.
4) Be sure to fi t a seal cap on any unused connectors.
4. When the high performance silencer is used for an
IP65 compliant manifold, prevent water from
splashing onto the silencer outlet.
Piping
CautionWhen piping to the product, be careful not to confuse
a vacuum port with an exhaust port. Otherwise this
can result in damage or reduced performance. Apply
compressed air after confirming that the piping is con-
nected correctly.
If each exhaust piping for the port exhaust ejectors
are connected and made into centralised piping, the
exhausted air will flow back into the exhaust path
which is not operating, and will then be exhausted
from the vacuum port. Exhaust individually.
